異常積累：org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode （轉載）

此異常是由于Spring提供的Open Session In View而引起的。
開啟OpenSessionInViewFilter這個過濾器的時候FlushMode就已經被默認設置為了MANUAL，如果FlushMode是MANUAL或NEVEL,在操作過程中 hibernate會將事務設置為readonly，所以在增加、刪除或修改操作過程中會出現該錯誤
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>flushMode</param-name>
<param-value>AUTO</param-value>
</init-param>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
